Background: This study evaluated temporal association of changes in BMI over time with major adverse cardiovascular event (MACE) in Korean middle-aged adults. Methods: Between 2001 and 2002, 6855 individuals from the Korean Genome and Epidemiology Study were included and followed up until 2014. The main predictor was the change in BMI determined using group-based trajectory modelling (decreasing, stable, and increasing) from the baseline to 4-, 6-, and 8-years of follow-up. The primary outcome was the occurrence of MACE. Results: During the mean 10.2 years follow-up, MACEs occurred in 350 (5.1 %) individuals. The median (interquartile rage) age of study population was 50 (44–59) years. In primary analysis with 4-year trajectory model, decreasing BMI trajectory was associated with a 1.41-fold higher risk of the MACEs (hazard ratio [HR], 1.41; 95 % confidence interval [CI], 1.06–1.91) compared with stable BMI trajectory. In secondary analyses with 6- and 8-year trajectory models, this association disappeared, and the corresponding HRs (95 % CIs) were 1.14 (0.81–1.61) and 0.98 (0.65–1.49), respectively. There were concomitant improvements in cardiometabolic risk factors in decreasing BMI group, but unfavorable risk burden remained up to 4 to 6 years. Conclusions: The initial 4-year weight loss was paradoxically associated with a higher risk of MACEs, probably due to residual cardiovascular burden. However, this association became null in participants with sustained weight loss ≥ 6 years, suggesting a possible lag effect of weight loss on MACEs.
